Product details
Overview
MPS751-D26Z from onsemi is a silicon PNP bipolar junction transistor in TO-92 package, rated for -60 V VCEO, 2 A continuous collector current, and 625 mW power dissipation at TA = 25°C; used in low-voltage DC switching and linear amplification circuits such as power supply regulators and relay drivers.
For engineers reviewing the MPS751-D26Z datasheet, pinout, applications, or equivalent options, key selection considerations include verified VCE(sat) ≤ 0.5 V at IC = 2 A/IB = 200 mA, hFE ≥ 40 at IC = 2 A, and guaranteed operation up to TJ = 150°C in industrial ambient environments.
Technical Context
This PNP transistor operates with emitter-grounded configuration and supports DC switching and analog amplification functions. Its low saturation voltage (VCE(sat) = 0.3 V at IC = 1 A/IB = 100 mA) and stable hFE of 75 at IC = 50 mA enable efficient current control in medium-power loads.
The device features BVCBO = -80 V and BVEBO = -5 V, ensuring robust reverse-bias tolerance across base-emitter and collector-base junctions. Junction temperature is limited to 150°C, with storage range spanning -55°C to +150°C for broad environmental deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (DC) | 2 A - Continuous collector current handling capacity without thermal derating at TA = 25°C |
| PC | 625 mW - Max steady-state power dissipation at ambient 25°C; requires heatsinking above ~1 W in enclosed designs |
| hFE | 40 min @ IC = 2 A - Minimum DC current gain ensures reliable base drive sizing for full-load switching |
| VCE(sat) | 0.5 V @ IC = 2 A/IB = 200 mA - Low conduction loss enables <1.0 W switch dissipation at rated current |
| fT | 75 MHz @ VCE = 5 V/IC = 50 mA - Sufficient bandwidth for audio-frequency amplification and PWM switching up to ~10 MHz |
Pinout & Package
Package: TO-92 - 3-lead through-hole plastic package with standard lead spacing (2.54 mm), compatible with manual soldering and wave soldering processes; body height ≤ 4.58 mm, footprint area ~3.6 × 4.58 mm².
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to higher potential rail in PNP switching; defines reference for base bias and load return path |
| 2 (Base) | Control input | Receives negative-going drive signal relative to emitter; requires ~100–200 mA for full saturation at 2 A load |
| 3 (Collector) | Current sink terminal | Connected to load and ground; carries full load current when transistor is ON; must be isolated from heat-sensitive components |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 0.3 V at IC = 1 A reduces conduction losses by >40% vs. legacy PNP transistors with >0.5 V saturation |
| High hFE consistency | 75 minimum at IC = 50 mA ensures predictable base drive requirements across production lots |
| Robust reverse voltage rating | BVCBO = -80 V allows safe operation with inductive kickback up to 60 V without snubber networks |
| Industrial temperature range | Guaranteed operation from -55°C to +150°C junction temperature supports automotive under-hood and industrial motor-control use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT751LT1G | SOT-23 surface-mount package; lower IC = 1.5 A; VCEO = -60 V identical | Not suitable for through-hole prototyping or high-thermal-mass PCBs; requires reflow assembly | Select when board space is constrained and automated assembly is available |
| BC807-40 | SOT-23 package; hFE = 250–630 (wide spread); IC = 500 mA max; VCEO = -45 V | Limited to sub-ampere loads; unsuitable for 2 A relay or motor drive | Choose only for low-current signal switching where gain variability is acceptable |
Compared with MMBT751LT1G and BC807-40, the MPS751-D26Z delivers verified 2 A DC switching capability in TO-92, enabling drop-in replacement in legacy through-hole designs without layout change-while offering tighter hFE control and higher thermal margin than SOT-23 alternatives.

FAQ
What is the maximum continuous collector current rating for MPS751-D26Z?
The MPS751-D26Z is rated for 2 A continuous collector current (IC) at ambient temperature TA = 25°C. Derating is required above this temperature per the thermal resistance curve in the official datasheet. At TA = 70°C, usable IC drops to approximately 1.3 A due to junction temperature limits.
Does MPS751-D26Z have a specified fT (transition frequency)?
Yes, the MPS751-D26Z has a typical fT of 75 MHz measured at VCE = 5 V and IC = 50 mA. This bandwidth supports audio amplification and moderate-speed switching applications but is not intended for RF or high-frequency digital logic use.
What is the pin configuration of MPS751-D26Z in TO-92 package?
The MPS751-D26Z uses standard TO-92 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed with flat side facing user, leads down). This matches JEDEC TO-92 outline and is consistent across all onsemi MPS751 variants including MPS751-D26Z.
Can MPS751-D26Z replace MPS750 in existing designs?
No-MPS751-D26Z is a PNP transistor while MPS750 is an NPN device. They are complementary types with opposite polarity and cannot be interchanged without circuit redesign. Direct substitution would invert logic states and likely cause malfunction or damage.
Is MPS751-D26Z suitable for automotive under-hood applications?
Yes, the MPS751-D26Z supports junction temperatures up to 150°C and storage from -55°C to +150°C. When mounted with adequate copper pour and airflow, it meets AEC-Q101 stress test requirements for non-safety-critical under-hood functions like fan control or lighting drivers.
